“…The open-loop transfer functions of the inductor current and the DC-link voltage of the inverter with respect to the shoot-through ratio is as follows [24,25]: In the low-frequency range of the amplitude-frequency characteristic curves, both the slopes of current and voltage curves gradually increased after compensation (Figure 3), indicating that the compensation could reduce the steady-state error of the system and improve the accuracy. As the inner loop, the current loop should have the characteristics of quick response and its bandwidth should be about 10 times of that of the outer loop.…”

The permanent magnet synchronous motor (PMSM) running above the base speed requires flux-weakening control, which is usually realized by the direct-axis demagnetization current generated by the vector control, thus leading to a decrease in the system efficiency in the flux-weakening region. In addition, the motor power output range is limited by the inverter output voltage and current level. In this paper, a Z-Source drive PMSM control system with adjustable DC-link voltage was proposed to improve the efficiency of the motor system. The proposed system was experimentally verified. The response time of DC-link voltage is 10 ms and the overshoot is 3%, indicating good dynamic characteristics. Compared with the flux-weakening scheme, the Z-Source inverter scheme can achieve higher efficiency (about 3%) when the PMSM speed was set to 650 r/min.

The application of renewable energy such as solar photovoltaic (PV), wind and fuel cells is becoming increasingly popular because of the environmental awareness and advances in technology coupled with decreasing manufacturing cost. Power electronic converters are usually used to convert the power from the renewable sources to match the load demand and grid requirement to improve the dynamic and steady-state characteristics of these green generation systems, to provide the maximum power point tracking (MPPT) control, and to integrate the energy storage system to solve the challenge of the intermittent nature of the renewable energy and the unpredictability of the load demand. In order to improve the efficiency and the power density of the overall circuit, the use of a three-port DC-DC converter, which includes a DC input port for the renewable source, a bidirectional DC input port for the energy storage system, and a DC output port for supplying the load, is a preferable solution to the traditional method using two DC-DC converters: one for the renewable sources and another for the energy storage system. In recent years, many DC-DC three-port converters have been proposed and reported in the literature. Each of these converters has its own topology and operating principle, which results in different complexities, different numbers of components, different reliability and efficiency. In this paper, a comparison of the features of different topologies of three-port DC-DC converters that have been proposed by different research groups is reviewed briefly. This review can be used as a guide for the appropriate selection of the suitable topology to meet the particular requirement of a system. The paper also discusses the potential research extension of the topologies from three-port DC-DC converters to three-port DC-AC inverters and how the voltage gain of the non-isolated three-port DC-DC converter can be improved.

 Abstract: Three phase multilevel inverters are frequently utilized in moderate and high power industries by minimizing the electromagnetic interference (EMI), enhancing the voltage profile and improving the power capacity. Although various converter topologies are developed for multilevel inverters (MLIs), Z-source MLIs are widely used for higher voltage applications. Z-source MLIs diminishes the total harmonic distortion (THD), and it has good stability and efficacy for various electrical power system applications. This paper aims to develop a three phase Z-source seven-level cascaded H-bridge (CHB) inverter with multicarrier PWM control techniques. The Z-source CHB inverter with multicarrier PWM control is modeled and its performance investigation with shoot through and non-shoot through modes is carried out in MATLAB/Simulink software platform.
